There are many advantages of OmniPage Professional 16 and I suggest you acquire the new version. OmniPage Professional 16 supports multiple documents and it is compatible with the latest Microsoft Office versions. Also, it provides on a single panel three screen views (Classic, Flexible and Quick Convert) and it can perform OCR operations. It can manage legal documents and it is equipped with a new, intuitive Workflow Assistant. All these features can be somehow covered by OmniPage SE 4.0, but not entirety and not with the same speed and professionalism. What is really unique at OmniPage Professional 16 is its capability to extract data from filled forms, mark and redact the text using the Text Editor and the File-it Assistant. For further information, I suggest you contact the developer.
